Release the natural beauty of your planted aquarium. The CO2 Natural Plant System helps you achieve beautiful, thriving live aquatic plants, and ultimately, a heathier aquarium. This simple to use system releases CO2 into your aquarium for up to 30 days. Employing a natural fermentation process for CO2 eliminates the need for inconvenient pressurized canisters. Easy to clean and restart. Complete system includes Fermentation Canister, a pateneted bubble counter/diffuser and 3 activator-stabilizer tablets. Each tablet set works up to one month.

This is a good starter kit for the beginner just getting into using CO2 injection. The bubble ladder is not the best method for delivering the CO2 but it does work. If this is used with a diffuser it works much better. Only good for tanks up to 30 gallons, beyond that it does little good.

A good starter CO2 generation unit. A little bulky as it hangs off the tank. I found the ladder works great but others seem to disagree. The unit will only get smelly if you leave the yeast in too long. If you change the sugar/yeast solution regularly there should be no issue. I would suggest getting a check valve for the output to avoid letting yeasty liquid into the tank.

Positive aspects of the product (pros):

ladder might be nice with better luck, reactor might be good design for something of it's small caliber, reactor hangs on tank

Cons:

bubbles hardly ever get into the diffuser, bubble rate is horrible

I am very dissappointed with this product. I didn't want an expensive Co2 system, but I wanted something that worked well. This is rated up to 20 gallons, and I bought it for my 30 gallon to make a small difference. However, I wouldn't even get it for a 20 gallon.

The reactor has some safety function of releasing gas if it builds up to be too much, and it hangs on the back to be out-of-the way, that's nice. The diffuser is nice, in my opinion, however, the way of getting bubbles into the diffuser seems very haphazard.

My big problem with this system is, it says it lasts for 28 days. I have had it running for 10 days. Day 2-4 it was working nicely, a bubble every 2 seconds and 90% getting into the diffuser. However, after day 5 it started to slow, and now at day 10 there's only a bubble every 26 seconds. It's supposed to last 28 days and I doubt 2 bubbles a minute, or less to come, is close at all to the "recommended amount". Also, in the last 5 days, less and less of the less bubbles are getting into the diffuser. At day 10, out of recommended 28, I'm getting a bubble every 26 seconds, and only 10% are getting into diffuser. That's right, 1 bubble every 5 minutes gets into the diffuser.

Some aspects of my tank:
My tank is not at any angle, so that isn't causing bubbles avoiding diffuser.
I did cut airtube and put a cheap check valve in, that might be slowing the bubbles per second somewhat, but I'm still very disappointed.

I don't know what everyone else is talking about but I had this on a 75 gallon and it made noticeable improvements to plant life. The key is to make your own co2 mix with yeast - water - sugar (Google how to) and change it out every week or sooner if you see it slowing down. But be careful and let it off gas OFF the tank for a couple hours on every refill or you will do what I did TWICE and blow a bunch of yeast into the tank. What a mess to clean up. Ha ha... But once you get it down it can add a lot of co2 for a small price. And I think the ladder works great, just make sure it is level and hose is connected right. I love this little thing. By the way, I rarely rate things a 10 but I really think this deserves it.
